I hope no one is seriously advocating for that position, so obviously the issue of "consistency" is more complicated.
An adult is able to weigh for themselves the risks and benefits of receiving a vaccine. A child is not able to weigh those risks and benefits, and it reasonable in general to have that decision made by their parents.
I suppose someone could say, to be consistent, that we should allow parents to decide for the child in his or her mother's womb how to weigh the risks and benefits of being aborted versus being born, but at least for a healthy child we would never accept that being born is a worse outcome than being dead.
So I think that protecting adults from unwanted vaccinations and protecting pre-birth children from being aborted can be a consistent stance, even though, I accept, the problem is much more complicated than even that.
Conversely, if someone becomes pregnant they can put the child up for adoption, and the state should make the father pay for that child's needs for the rest of their life. If the father knew that the mother was under the influence of drugs, he should also spend a large portion of his life in prison learning to care about other people.
As for the pregnancy idea, sure, in a perfect place with great social support, little stigmatizing of sex & adoption, and a legal system that can impose on the father (from flight or responsibility). I don’t see that anywhere, so how would we get there?
I never was taught that cold sores are a virus transmitted via saliva contact, including sharing a glass, ditto for mono. I was just told kissing or engaging in sexual behavior led to terminal illness or pregnancy. Also if one becomes pregnant there is strong pressure from parents on both sides to marry and raise the child despite a total lack of maturity or social or romantic connection. This is the experience of many Americans.
How do you define proper support for adoption? How can you measure that on a scale of that vs a scale from outlawing abortion to proper abortion? Also what is proper abortion?
A strong factor of oppression is a restriction on mobility. For a 15 year old girl, how does she ask for a ride to the next state? When I was 15 I felt shady riding my bike ten miles. We are almost certainly going to talk past each other. Good day to you.
